Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Anordnung zur Dichtheitsprobe der Hauptluftleitung an selbsttätigen Druckluftbremsen von Eisenbahnfahrzeugen. Sie dient dazu, unabhängig von störenden Einflüssen die Dichtheitsprobe nach Kriterien durchzuführen, die ein eindeutiges Prüfergebnis zulassen.The invention relates to a method and an arrangement for the leak test Main air line on automatic air brakes of railway vehicles. It serves to check the tightness independently of disturbing influences Carrying out criteria that allow a clear test result.
Um Bremsproben an Eisenbahnfahrzeugen nach der Zugbildung zu rationalisieren, werden stationäre Bremsprobegeräte eingesetzt. Da hierbei eine Zufuhr von Druckluft über gesonderte externe Einrichtungen erfolgt, kann auf eine Druckluftversorgung durch ein an die Hauptluftleitung angeschlossenes Triebfahrzeug verzichtet werden.In order to rationalize brake tests on railway vehicles after train formation, stationary brake test devices are used. Because this is a feed of compressed air via separate external devices can be carried out on a Compressed air supply from a locomotive connected to the main air line to be dispensed with.
Neben dem eigentlichen Füllen der Hauptluftleitung auf einen vorgeschriebenen Druck, einem Einbremsen und einem anschließenden Lösen der Bremsen gehört die Durchführung einer Dichtheitsprobe zu den wesentlichen wie auch vorgeschriebenen Maßnahmen bei der Durchführung von Bremsproben.In addition to actually filling the main air line to a prescribed one Pressure, braking and then releasing the brakes performing a leak test is one of the most important ones also prescribed measures when carrying out brake tests.
Bei der Dichtheitsprobe wird über ein zumeist am Bremsprobegerät befindliches Ventil die Verbindung des Füllanschlusses zur Hauptluftleitung des Zuges unterbrochen. In dem nun abgeschlossenen Volumen, im Wesentlichen bestehend aus dem Leitungsvolumen der Zuleitung und der Hauptluftleitung, wird ein gegebenenfalls eintretender Druckabfall über eine vorgeschriebene Zeitspanne hinweg durch das Bremsprobegerät messtechnisch erfasst. Zur anschließenden Beurteilung eines dichten oder undichten Bremssystems wird ein maximal zulässiger Wert für den eingetretenen Druckabfall herangezogen, der in entsprechenden Vorschriften formuliert ist.The leak test is carried out using a test device usually located on the brake test device Valve the connection of the filling connection to the main air line of the train interrupted. In the now closed volume, essentially consisting from the line volume of the supply line and the main air line, a any pressure drop that occurs over a prescribed period of time measured by the brake tester. To the subsequent one Assessment of a leaky or leaky braking system becomes a maximum allowable Value for the pressure drop occurred, which in corresponding Regulations is formulated.
Naturgemäß ist die Quantifizierung eines eventuellen Leckstromes auf dem Wege der Bestimmung des Druckabfalls nur dann möglich, wenn dieser auf einen bestimmten konstanten Ausgangsdruck sowie auf ein bestimmtes konstantes Volumen bezogen wird.Naturally, the quantification of a possible leakage current on the It is only possible to determine the pressure drop if this is due to a certain constant outlet pressure as well as a certain constant Volume is obtained.
Ein konstanter Ausgangsdruck ist in der Praxis gewährleistet, da die Hauptluftleitung vor Ausführung der Dichtheitsprobe bereits auf einen genau festgelegten Druck aufzufüllen ist. Von einem konstanten Volumen dagegen kann in aller Regel nicht ausgegangen werden. Dieses variiert allein schon wegen der unterschiedlichen Längen der zusammenzustellenden Züge. In den schon erwähnten Vorschriften für den Ablauf der Dichtheitsprobe werden jedoch keine Angaben hinsichtlich der Zuglänge getroffen, für die der maximal zulässige Druckabfall gilt. Weiterhin wird die Größe des Volumen beeinflusst durch die Länge der Luftleitung zwischen dem Bremsprobegerät und dem Anschluss an den zu prüfenden Zug.A constant outlet pressure is guaranteed in practice because the main air line before carrying out the leak test to a precisely defined one Pressure must be replenished. On the other hand, from a constant volume generally not be assumed. This varies simply because of the different lengths of the trains to be put together. In the already mentioned However, there are no regulations for the sequence of the leak test Information regarding the train length for which the maximum allowed Pressure drop applies. Furthermore, the size of the volume is influenced by the Length of the air line between the brake test device and the connection the train to be checked.
Inwieweit die Größe des eingeschlossenen Volumens ein Prüfergebnis ausschlaggebend beeinflusst, ist bereits daraus erkennbar, dass die Dichtheit eines Zugverbandes praktisch herbeigeführt werden kann, indem diesem einzelne Wagen mit hinreichend dichten Bremskupplungen an den Hauptluftleitungen hinzugefügt werden.To what extent the size of the enclosed volume is decisive for a test result is already evident from the fact that the tightness of a Train association can be practically brought about by this individual Cars with sufficiently tight brake clutches on the main air lines to be added.
Um die daraus entstehenden Fehler möglichst gering zu hatten, müssen in der Praxis einige begleitende Maßnahmen bei der Durchführung der Dichtheitsprobe beachtet und eingehalten werden. Dies betrifft insbesondere eine Einschränkung der Leitungslänge zwischen dem Bremsprobegerät und dem Anschluss an die Hauptluftleitung des Zuges. Zweckmäßig ist außerdem, das absperrende Ventil samt Drucksensor von dem eigentlichen Bremsprobegerät weg und hin an den zu prüfenden Zug zu verlegen. Diese Maßnahmen schränken allerdings den Komfort ein, den Bremsprobegeräte und insbesondere automatisch arbeitende Anlagen normalerweise bieten. Eine eindeutige Bewertung des Prüfergebnisses lassen sie indessen nicht zu.In order to minimize the resulting errors, in practice some accompanying measures when carrying out the leak test be observed and complied with. This applies in particular to a restriction the cable length between the brake test device and the connection to the main air duct of the train. It is also expedient to shut off Valve and pressure sensor away from the actual brake test device and move it to the train under test. Limit these measures however, the comfort, the brake test devices and in particular automatically normally offer working systems. A clear assessment of the However, they do not allow test results.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Anordnung zur Dichtheitsprobe der Hauptluftleitung an selbsttätigen Druckluftbremsen zu schaffen, die es erlauben, eine Dichtheitsprobe unabhängig von störenden Einflüssen nach Kriterien durchzuführen, die ein eindeutiges Prüfergebnis zulassen.The invention has for its object a method and an arrangement to test the tightness of the main air line on automatic air brakes create that allow a leak test regardless of disruptive influences according to criteria that allow a clear test result.
Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Hauptanspruches erfindungsgemäß gelöst, indem parallel zu einem Magnetventil mit größerem Querschnitt für das Füllen der Hauptluftleitung in Strömungsrichtung ein Bypass mit einem zweiten Magnetventil kleineren Querschnittes zusammen mit einem Volumenstromsensor angeordnet ist, dass das Füllen der Hauptluftleitung durch Öffnen des Magnetventils mit größerem Querschnitt erfolgt, während das Magnetventil kleineren Querschnittes geschlossen bleibt, und dass für die Dichtheitsprobe das Magnetventil größeren Querschnittes geschlossen und dabei das zweite Magnetventil kleineren Querschnittes geöffnet wird, über das ein Volumenstrom nachgefüllt wird, der für die Druckerhaltung in der Hauptluftleitung mindestens erforderlich ist, und dass der nachfüllende Volumenstrom gemessen wird und ein Kriterium für die Dichtheit der Hauptluftleitung ist.This task is in connection with the preamble of the main claim solved according to the invention by parallel to a solenoid valve with a larger Cross-section for filling the main air line in the flow direction a bypass with a second solenoid valve of smaller cross section together with a Volume flow sensor is arranged that the main air line is filled by Opening of the solenoid valve with a larger cross-section takes place while the solenoid valve smaller cross section remains closed, and that for the leak test the solenoid valve of larger cross-section closed while doing so the second solenoid valve of smaller cross-section is opened, via the one Volume flow is refilled, which is used to maintain pressure in the main air line is at least necessary, and that the replenishing volume flow is measured and is a criterion for the tightness of the main air line.
Eine vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch 4 angegeben.
Danach besteht der Volumenstromsensor aus einem Laminarrohr, an
dem eine Druckdifferenz zwischen seinem Eingang und seinem Ausgang gemessen
wird und sich diese Druckdifferenz proportional zu dem zu messenden
Volumenstrom verhält und somit ein Maß für diesen ist.An advantageous embodiment of the invention is specified in
Der Volumenstrom zum Nachfüllen der abgesperrten Hauptluftleitung über das zweite Magnetventil kleineren Querschnittes kann wegen eines vorgeschalteten Druckreglers für den Füllvorgang nur maximal so groß werden wie derjenige Volumenstrom, der durch Leckfluss verloren geht. Bleibt während dieses Nachfüllens der Druck innerhalb der Hauptluftleitung mindestens oberhalb eines vorgegebenen Wertes für einen Toleranzbereich, so ist der für das Nachfüllen erforderliche Volumenstrom gleich groß dem abfließenden Leckstrom und somit ein Maß für die Dichtheit. Die Hauptluftleitung kann folglich dann als dicht beurteilt werden, wenn dieser Volumenstrom einen vorgegebenen Vergleichswert für einen maximalen Leckstrom nicht überschreltet.The volume flow for refilling the blocked main air line via the second solenoid valve of smaller cross section can be connected upstream Pressure regulator for the filling process can only be as large as the volume flow that is lost due to leakage flow. Stay while this refilling the pressure within the main air line at least above of a predetermined value for a tolerance range, then that for the Refill required volume flow equal to the flowing leakage flow and thus a measure of the tightness. The main air line can therefore then be judged as tight if this volume flow a predetermined Comparison value for a maximum leakage current not exceeded.
Das Erkennen eines Druckabfalls während des Nachfüllens in der Hauptluftleitung auf Werte unterhalb dieses Toleranzbereiches weist dagegen auf eine Erschöpfung des zum Nachfüllen maximal verfügbaren Volumenstromes hin. Wenn dieser maximal verfügbare Volumenstrom in einer besonderen Ausführungsform der Erfindung so dimensioniert ist, dass er dem maximal zulässigen Leckstrom entspricht, so ist auch das Erfassen eines Druckabfalls unabhängig von seiner Größe gleichzusetzen mit dem Erkennen einer undichten Hauptluftleitung und erübrigt zudem in Übereinstimmung mit dem Anspruch 2 die gesonderte Erfassung des nachgefüllten Volumenstromes.Detecting a pressure drop during refill in the main air line on the other hand, values below this tolerance range indicate a Exhaustion of the maximum volume flow available for refilling. If this maximum available volume flow in a special embodiment the invention is dimensioned so that it the maximum allowable Leakage current corresponds, the detection of a pressure drop is also independent its size equates to the detection of a leaky main air line and also dispenses with the separate in accordance with claim 2 Detection of the refilled volume flow.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.
Es zeigt Figur 1 einen schematischen Aufbau einer erfindungsgemäßen Anordnung zur Durchführung der Dichtheitsprobe.1 shows a schematic structure of an arrangement according to the invention to carry out the leak test.
Einem Magnetventil größeren Querschnittes 1 ist als Bypass in Strömungsrichtung
zur Hauptluftleitung 2 eines Zuges 3 ein Magnetventil kleineren Querschnittes
4 und ein Volumenstromsensor in der Form eines Laminarrohres 5
parallel geschaltet. Dem Laminarrohr 5 ist weiterhin ein Rückschlagventil 6 mit
Durchströmrichtung in Richtung zur Hauptluftleitung 2 des Zuges 3 parallel geschaltet.
Das Rückschlagventil 6 weist einen definierten Öffnungsdruck auf. Der
Querschnitt und der Messbereich des Laminarrohres 5 sind so abgestimmt,
dass sie den für die Messaufgabe relevanten Volumenströmen entsprechen.A solenoid valve of
Ein Differenzdrucksensor 7 ist so mit dem Laminarrohr 5 verbunden, dass er
die Druckwerte am Eingang und am Ausgang des Laminarrohres 5 aufnehmen
und in ein elektrisches Signal wandeln kann, das einer Steuereinrichtung 8 zugeführt
wird.A
An der Hauptluftleitung 2 ist ein Drucksensor 9 angeschlossen, der an seinem
Ausgang ein dem Druck proportionales elektrisches Signal erzeugt, das
ebenfalls mit der Steuereinrichtung 8 verbunden ist.A
Für das Auffüllen der Hauptluftleitung 2 wird ein Volumenstrom Qv über einen
Druckregler am Bremsprobegerät und über das geöffnete Magnetventil
größeren Querschnittes 1 in die Hauptluftleitung 2 geführt. Es wird so ein
schnelles Aufladen mit einem hinreichend großen Volumenstrom auf einen
Druck ermöglicht, der dem eingestellten Wert des Druckreglers entspricht. Das
Magnetventil kleineren Querschnittes 4 bleibt dabei noch geschlossen.For filling the main air line 2, a volume flow Q v is fed into the main air line 2 via a pressure regulator on the brake test device and via the open solenoid valve of
Zur Durchführung der Dichtheitsprobe wird das Magnetventil größeren Querschnittes
1 geschlossen und dann das Magnetventil kleineren Querschnittes 4
geöffnet. Jetzt ist das Bremssystem, bestehend aus Hauptluftleitung 2 und Zuleitung
zur Hauptluftleitung 2, vom Volumenstrom Qv weitgehend abgetrennt
und wird nur noch über das Magnetventil kleineren Querschnittes 4 und das
Laminarrohr 5 weiter nachgefüllt. Während des Nachfüllens überwacht der
Drucksensor 9 den Druck in der Hauptluftleitung-2. Ein auftretender Druckabfall
in der Hauptluftleitung 2 unter die Grenze eines Toleranzbereiches kennzeichnet
die Erschöpfung des nachfüllenden Volumenstromes und weist auf einen
erheblichen Leckstrom in der Hauptluftleitung hin.To carry out the leak test, the solenoid valve of
Liegt die über den Drucksensor 9 ermittelte Druckeinhaltung korrekt innerhalb
des Toleranzbereiches, so kann über den Druckdifferenzsensor 7 die
Druckdifferenz an dem Laminarrohr 5 zwischen seinem Eingang und seinem
Ausgang gemessen werden. Diese Druckdifferenz verhält sich direkt proportional
zu dem durch das Laminarrohr 5 strömenden Volumenstrom und ist somit
ein Maß für diesen. Dabei dient das Rückschlagventil 6 als Schutz für den Differenzdrucksensor
7. Der Messwert über die Höhe des Volumenstromes durch
das Laminarrohr 5 wird an die Steuereinheit 8 geleitet und dort mit einem maximal
zulässigen Wert für den Leckstrom verglichen. Im Ergebnis dieses Vergleiches
werden Signale zur Kennzeichnung einer dichten oder undichten
Hauptluftleitung 2 ausgegeben und angezeigt.Is the pressure maintenance determined by the
Nach beendeter Dichtheitsprobe wird das Magnetventil kleineren Querschnittes
4 geschlossen und das Magnetventil größeren Querschnittes erneut
geöffnet. After the leak test has been completed, the solenoid valve becomes smaller in
